When you delete the only character in a on-character-word followed by a space, the space gets deleted too.

Reproducible: Always

Steps to Reproduce:
1. Go to http://www.mozilla.org/editor/midasdemo/
2. Type "a b c"
3. Place the cursor immediately to the left of the "b"
4. Press the delete key
 --> Both the "b" and the following space are deleted. Only the "b" should have been deleted.
5. Press the delete key again
 --> Nothing happens, but the user would expect "c" to be deleted now.



This bug does not happen in Firefox 3.0 .

This affects Google properties.

This works fine for me. Can this be reproduced in safe-mode / with a new profile?

If so, can you please provide more information to reproduce the bug?

Yes it reproduces in safe mode. I had just installed a fresh 3.5.3 to reproduce it so it is with a new profile. Also just got it to reproduce on 3.5.3 on the mac (you have to press fn+delete).

The initial html before pressing delete is "a b c<br>". If you look at the resulting html in 3.0, the correct result is "a&nbsp; c<br>". In 3.5.3, the resulting html is just "a c<br>". Maybe the new code is "forgetting" to convert the first space into an nbsp, and then when it sees two adjoining soft spaces it merges them?

With the latest Firefox 3.5 I get the result: a&nbsp; c <br>
after deleting the b .
The Firefox profile is not in the installation directory. Uninstalling/reinstalling Firefox will leave the profile untouched.
The latest Firefox 3.5 (Shiretoko) test nightlies can be downloaded here: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-1.9.1/

Great! It's WORKSFORME because the code that fixed it is unknown.
